Stop Valve for Climatronic (N422)

[mi1rmac]

First - let me apologize if this has been covered somewhere but I have searched high and low and found nothing regarding this topic for our engines.

TLDR: I have a code for the N422 valve.
- I am unable to find the P/N or the location of where this valve is on the vehicle.

Code Info:
03220 - Stop Valve for Coolant for Climatronic (N422)

I guess on later model B8's and B8.5's this valve was eliminated however on earlier models it was still used. Any help is greatly appreciated!

So The Climatronic Refrigerant Shut-Off Valve “N422” actuates the shut-off valve by vacuum.
There a vacuum hose behind the TB , # 1 is the disconnect for the climatronic refrigerant shut-off valve

And #7 is Coolant Switch-Off Valve
